Answer:
The statement is True.
Explanation:
If you want to lose a pound, you should aim to reduce calories from your diet over it. Such as in one week there should be a deficit of 3500 calories, which means you should take 500 less calories daily in order to lose one pound in a week. 3500 calories constitute one pound. If your calorie recommendation is 1500 calories per day, then you should take 1000 calories in a day in order to have a deficit of 500 calories from your recommended calorie intake. This will result in losing one pound in a week.
Answer:
About 500 calories a day.
Explanation:
There are approximately 3,500 calories equivalent to 1 pound. 7 days a week.
c/t=e c- calories equal to the amount to lose. t= time to lose it. e= equivalent to total.
Tissues are composed of the same kind of cells
Explanation:
In any living organism, cells form the basic unit of life.
Similar kind of cells groups together to form tissues and performs a similar kind of function in complex organisms.
Similar kind of tissues groups together and develops to form the organ systems in higher order animals like the vertebrates.
The tissues are derived from the embryonic layers – ectoderm, mesoderm, endoderm - which gives rise to respective organ system in vertebrates.
The four major tissue types are epithelial, connective, muscle, and nervous tissues.
Epithelial tissues are a group of cells which protects and cover the lining of the skin as well as the visceral organs.
Connective tissues are present in ligaments and tendons attached to bones and other areas and provide flexibility and elasticity. Cartilage, adipose tissue, and blood are all made up of connective tissue.
Muscle tissues form the muscles of the body. They are of three types – striated or skeletal, cardiac, and smooth muscles
Nervous tissues are formed by grouping of nerve cells or neurons and conducts impulses

A. True
B. False
The chromosomal and single-gene disorders are hereditary in nature and therefore, can be transmitted from parents to offspring.
Further Explanation:
A change or mutation in a particular gene of DNA results in a specific inheritance pattern and is called single-gene disorder. Such disorders are rare in the population and can be tracked easily within a family. The probability of its occurrence in the future generation can also be predicted. This disorder is categorized into three types: recessive, dominant, and X-linked.
When the dominant allele of a gene is affected it suppresses the expression of the other healthy allele is it recessive or dominant. It usually occurs in the heterozygous state. As a result the mutant allele gets expressed and displays the symptoms of the disease. The mutated dominant allele is passed onto every generation and therefore, the disease is expressed in everyone in the family. For example, Huntington’s disease is a disorder in the brain in which a single gene on chromosome 4 is defective.
In recessive disorders, the recessive allele is defective and the disease occurs only in the homozygous state when both the defective alleles are present. In case of heterozygous state, the healthy allele can suppress the expression of the recessive mutant allele. In order to transfer the disease to the offspring, both the parents must contain the defective allele. For example, sickle cell anemia.
The presence of defective X chromosome results in X-linked diseases. It can be either a recessive or dominant disorder. These disorders are mostly seen in males as they contain only one copy of the X- chromosome. Examples are hemophilia and Rett syndrome.
A mutation or abnormality in a person’s chromosomes results in chromosomal disorders. Down syndrome represents a chromosomal disorder in which an extra copy of chromosome 21 is usually present in an embryo. The extra copy is transmitted genetically from either parent to the offspring and causes developmental changes in the embryo as a result of which the child becomes mentally and physically abnormal.
